Be it known that I, ELMER..A.,WUITZ, a citizen of the United States, residing at Barberton, in the county of Summit and State of Ohio, have invented certain new and useful Improvements 'in' Steam Generators and Regulators forTurbines; and I do declare the followin to be a'full, clear,

' and'exact description 0t th .invention, such "as will enable others skilled in .the art to which it appe'rtains to make: anduse the same. H I

This invention relates-to a steam gen: erator and regulator for turbines.-

One object-of the present invention. is 15.

provide imeans for generatinglthe steam with a less consumption of fuel t fore been possible. l v v A further object of the invention is'to rovide .means' for regulating the pressure of the steam in the boiler, or for keeping the pressure within certain limits,so that the turbinewill operate .at an approximately constant speed. With these and other objects in view the invention consists of certain novel features of construction, combination and arrange ment of parts as will be more fully described and particularly pointed out pended claims.

12. An air piston, 13, is reciprocatorily t'ua'ted by an eccentric, '14,.on the turbine shaft, 15. A water supply pipe comprising the upper portion; 16 and the lower portion, 17, extends from 2, to a 'po'mt somewhat beyond the lower end pipe, 17, may be connected with a source of watersu'pply in any desired manner.v A piston casing, 18, is arranged at-the junc and outer portions, 16 and 17,;of' the water supply pipe, in which is mounted the piston, 19, which is also op.-v erated by a cam on the turbine shaft, 15.

vided with the check valve, 20,. and at a point above the check valve, with the manu ally operated valve, 21, while the upper portion thereof is provided with a manually the lower end of the boiler,

The lower portion, 17 of this plpe is prooperated valve, 22,'and at a point above the T latter with a check valve, 23. v v

The lower end of the boiler, 2, is provided with the combustion chamber, 24, which may be of any suitable lower end of which fits per end of the fuel and air supply pipe, 25,

the upper end of the tank, -5, and ispr'ovided with the manually operated valve, 26.

A shield,

27, incloses the upper endfof the pipe, 25.'A pipe,' 28, extends from the water supply pipe'at the junction of the upper and lower portions 16 and .17, thereof, to the pipe25 at a point somewhat beneath the, lower end of the combustion chamber,,24.. The-end of this pipe, immediately adjacent the pipe 25 is prov1ded with; a manually pperated valve, 29, while the opposite end. 1s oms somewhat nearer the water rovided with a. check valve, 30, and at a upp y pipe with a 'manually operated valve, 31.. Thelfirst mentioned en'd ofthe pipe 28, is

also provided w th a by-pass 32, which is also equipped with a manually operated valve, 33.

- The pipe, 25, is provided at one side and at a pomt somewhat beneath the lower end of the combustion chamber, 24 with the pieton chamber, 34, in which is mounted the piston, 35. This piston is provided contact, 36, the outer end, 37, of whichfis normallyheld in contact or engagement with 38, by means of the spring, 39, is disposed within the plston chamwhich form andin the," I or extends the upthe lower end of wh'ch communicates w1th with a f ber, 34., A solenoid 40 is arranged beneath with the contact, 38 by the conductor, 41.

the piston chamber 34, and is connected The opposite end of the solenoid is, connected with the battery, 42, or other source of 'currentby the wire, 43. A conductor, 44,--

leads from the opposite side of the "battery and is provided with the electrode, '45, which extends into the upper end of the shield, 27, at a point immediately above the upper end of the fuel supply pipe, 25, and being disposed adjacent to a second electrode, 46, connected with the contact, 36, by the conductor, 47. A cut-ofi valve, 48,is pivotally mounted upon a cylindrical extension, 49, formed at thelower end of ,the'pipe, 25, and is rovided with the armature, 50. d

In t e operation of the device, air is pumpedinto the pipe, 6, and into the tank, 5, by the piston, 13. As the air passes into the tank, 5, which is filled with gasolene, it mlxes with the gasolene and passes to the upper end of the supply pipe, 25, Where it isignited by the spark WlllCll jumps across the electrodes, and 46. To cause the current to pass between the electrodes 45 and 46 when the circuit is closed, an induction coil I'is'arranged in the circuit, of which coil 71 is the primary and z" the secondary. After this air and gasolene mixture is thus lgnlted the products pass through the com bustion chamber into the boiler, 2, and to the upper end of the latter, and in doing so.

all heat is absorbed by the water in the boiler which eventually turns into steam. When thewater in the boiler becomes too low the manually operated valves 22 and2'9 are elosed'while the valves 31 and 33 areopened. When the steam in the boiler reaches 1ts high ressure limit, the piston, 1s forced outwardly against the action of the spring, 39, which disengages the contact, 36, with the contact, 38, when the circuit isbroken and the solenoid demagnetiZed-which permits the armature, 50, to drop when the valve, 48, closesand-cuts off fufther supplyof-the heating fuel or the air and gasolene mixture to the combustion chamber. After the steam pressure falls below the maximum or highest limit, the piston, 35,, is returned to normalposition by the action of the spring, 39, which again brings thecontact 36, into engagement with the contact, 38, which closes the circuit and energizes the solenoid. When the solenoid is thus energized, the armature 50 is again re-i tracted and-the valve, 48, opened which permits" the fuel to again pass through the pipe, 25. The tank 5 is charged with air as fast as it is -utilized,- by the' piston 13 which pumps air through the pipe 10 to the tank. Howeven, should the piston Jsupply air to the tank fasterthan it is used, when the resulting pressure exerted against the face53of the cut-off valve 51 arranged in pipe 6 exceeds the steam pressure exerted against the face 52 of said valve-the valve valve 12 in ipe 10 is then closed and valve 9 opened, w len the air in pipe 6 is allowed to escape through the pipe 8 and the valve,

.51 is permitted to return tonormal position, when steam again passes to the turbine. When the water becomes low in the boiler, it is recharged by closing valves 22 and 29 and opening valves 31 and 33. The piston,

19, then draws water through the lower por- 'is moved into steam cut-off position. .The

tion, 17, of the water supply .pipe and forces it through the pipe, 28 and the by-p s pipe 32, into the combustion chamber of the boiler'. After the water reaches the proper height in the boiler and the engine is again running, the valve, 33, may be closed and the valve, 29, may be opened so that the water will pass through the u per end of theisupply pipe, '25.: "This is one to ,keep

the supply pipe filled with water which H trickles down through the pipe, 25, into the gasolene tank, 5, as each bubble-of air and gasolene passes upward through the water in the same pipe, thus keeping the upper end of' the tank and, the entire supply pipe filled gasolene'bub- I and heating systems, comprising a boiler, a 1
